ENERGY STAR Labeled Building Profile

Arden's 5161 Lankershim property located at 5161 Lankershim, N. Hollywood, California is a 178,317 rentable square foot building that is 94% occupied. As part of the company's ongoing energy efficiency program, 5161 Lankershim, constructed in 1985, was chosen as a candidate for a building wide lighting retrofit. The building also has an Andover EMS that controls building HVAC at optimum conditions. These additions were conceived as part of the overall efficiency enhancement at the property. A typical Arden lighting retrofit was accomplished by replacing T-12 light tubes with T-8 light tubes and installing electronic ballasts. The incandescent and fluorescent exit signs were replaced with LED exit signs using only two watts per fixture. Also installed were occupancy sensors throughout the building to reduce unoccupied lighting energy.

In addition to all the lighting and mechanical upgrades, many no cost / low cost measures were taken that reduced energy consumption. These included:

Demand side management programs including monitoring the kW peak demand and monthly review of peak demand.

Reducing simultaneous heating and cooling to a minimum. This is largely due to spreading the load over time using optimal start strategy and utilizing the EMS.

Pre-cooling and pre-heating the building at night during low energy use / cost times.

Arden's engineering department recognizes the financial impact of electrical demand charges, and as such, targets their operation towards peak demand reduction. By monitoring electrical demand levels and establishing a peak target, the energy management systems are programmed to selectively reset equipment to keep the demand within defined limits while never compromising occupant comfort.

The payback for these initiatives is approximately three and a half years with a marked increase in tenant satisfaction and comfort.
